Carol,
This is sort of an "I don't know" answer to your questions, but with a
few "Maybe"s scattered throughout.

The short answer is "In the Unix System Services Messages and
Codes" manual. The last 2 bytes are a reason code; the first 2 are a
reason qualifier. Unfortunately I can't find 1004, but I may have been
looking in an old manual.

Uh, yup. I've seen it before. I searched on it and up popped
PQ70749: TCPIP SUPPLIED SOCKET API'S GETADDRINFO CALL FAILS TO
RESOLVE PROVIDED NAME TO IP ADDRESS
...
GetAddrInfo Failed: RetVal = -1, RC = 1, Reason = 0x78AE1004
Are you by any chance still on z/OS 1.2 or 1.4? If so, you might be
running into this. There's a LOT not said in the APAR; something else
is needed to cause this error. (We never ran into it on either 1.2 or
1.4.) I suspect there are other non-bug reasons to get this.

This says that the Resolver first looked for local host tables and didn't
find any. It doesn't mention trying looking for a remote name server
before it fails. That seems odd. There should have been a bunch of
stuff prior to the lines you included that relate to your RESOLVER parms
in TCPDATA. It would be helpful to see these. They will say whether
you are trying to use name servers or not, what order you search, etc.
Could you show those? Feel free to obscure dataset names, IP addrs,
etc, but please include the lines containing that info. It should look
something like
res_init Resolver values:
Global Tcp/Ip Dataset = None
Default Tcp/Ip Dataset = None
Local Tcp/Ip Dataset = SYS1.TCPPARMS(TCPDATA)
Translation Table = SYS1.TCPIP.STANDARD.TCPXLBIN
UserId/JobName = zzzzzzzz
Caller API = TCP/IP Sockets Extended
Caller Mode = EBCDIC
(L) DataSetPrefix = SYS1.TCPIP
(L) HostName = SYSA
(L) TcpIpJobName = TCPIP
(L) Search = abcde.COM
(L) NameServer = aaa.bbb.ccc.ddd
(L) NsPortAddr = 53 (L) ResolverTimeout = 10
(L) ResolveVia = UDP (L) ResolverUdpRetries = 2
(*) Options NDots = 1
(*) SockNoTestStor
(*) AlwaysWto = NO (L) MessageCase = MIX
(*) LookUp = DNS LOCAL
res_init Succeeded
